    Unknown(UnknownVariantValue),
}Expand description
When writing a match expression against SearchResourcesSimpleCriterionKey, it is important to ensure
your code is forward-compatible. That is, if a match arm handles a case for a
feature that is supported by the service but has not been represented as an enum
variant in a current version of SDK, your code should continue to work when you
upgrade SDK to a future version in which the enum does include a variant for that
feature.
Here is an example of how you can make a match expression forward-compatible:
# let searchresourcessimplecriterionkey = unimplemented!();
match searchresourcessimplecriterionkey {
    SearchResourcesSimpleCriterionKey::AccountId => { /* ... */ },
    SearchResourcesSimpleCriterionKey::S3BucketEffectivePermission => { /* ... */ },
    SearchResourcesSimpleCriterionKey::S3BucketName => { /* ... */ },
    SearchResourcesSimpleCriterionKey::S3BucketSharedAccess => { /* ... */ },
    other @ _ if other.as_str() == "NewFeature" => { /* handles a case for `NewFeature` */ },
    _ => { /* ... */ },
}
The above code demonstrates that when searchresourcessimplecriterionkey represents
NewFeature, the execution path will lead to the second last match arm,
even though the enum does not contain a variant SearchResourcesSimpleCriterionKey::NewFeature
in the current version of SDK. The reason is that the variable other,
created by the @ operator, is bound to
SearchResourcesSimpleCriterionKey::Unknown(UnknownVariantValue("NewFeature".to_owned()))
and calling as_str on it yields "NewFeature".
This match expression is forward-compatible when executed with a newer
version of SDK where the variant SearchResourcesSimpleCriterionKey::NewFeature is defined.
Specifically, when searchresourcessimplecriterionkey represents NewFeature,
the execution path will hit the second last match arm as before by virtue of
calling as_str on SearchResourcesSimpleCriterionKey::NewFeature also yielding "NewFeature".
Explicitly matching on the Unknown variant should
be avoided for two reasons:
- The inner data UnknownVariantValueis opaque, and no further information can be extracted.
- It might inadvertently shadow other intended match arms.
The property to use in a condition that filters the query results. Valid values are:
